Mess free coloring system

摘要

A mess-free coloring system comprising a coloring medium and optionally one or more coloring utensils is disclosed. The coloring medium can include a substrate with or without decorative effects and one or more coating layers on a surface of the substrate. In various examples, the one or more coating layers include a color-triggering developer, e.g., in the form of a substantially clear resin, and an opaque pigment. Decorative effects integrated with or disposed on the substrate, while initially obscured by the one or more coating layers, can be revealed when the coating layers are mixed with at least one color precursor stored and dispensed from a coloring utensil. The opaque pigment is selected and configured such that, upon receipt of at least one color precursor by the one or more coating layers, a change in the pigment's reflective index occurs as the pigment dissolves into the clear resin developer.

主权项

1. A mess-free coloring system, comprising:
a coloring medium, including:
a substrate having a surface; anda coating layer disposed above the surface of the substrate, the coating layer including a color-triggering developer and a visually opaque pigment, the coating layer visually obscuring at least a portion of the surface of the substrate; a color precursor composition, comprising a color precursor, and formulated such that upon application of the color precursor composition to the coating layer, contact between the color precursor composition and the visually opaque pigment causes the initially visually opaque pigment to change in reflective index as it dissolves into the color-triggering developer, thereby becoming more visually transparent as compared to its state before contact with the color precursor composition, revealing at least a portion of the surface of the substrate initially visually obscured by the coating layer, and contact between the color precursor composition and the color-triggering developer chemically activates or initiates the conversion of the color precursor into chromophores to form and substantially permanently capture a colored mark on the coloring medium.
